If I sketch a square, extrude the square into a cube, and then sketch ANOTHER feature into the cube’s surface (a circle, say, which I will extrude (subtract) through the square’s body), all is well until I MOVE the original body. While the body moves, the sketch and feature (subtracted circle) remain put, and thus they disappear from the body altogether DUE to the move. I realize that sketches don’t stick to their bodies, but surely Shapr3d accommodates the moving of complicated bodies AND the features you have incorporated into them? Surely. Right?
They do, you just need to constrain your sketches to the body.
